Metal Roof Slope Transition

This is a fairly common roof detail.

Metal roof slope transition.

We need to do something where that change happens so the panels can go down and water can come off hit the lower slope and come off the roof. Retro split storm collar all style medium retro split storm collar flashing. Low slope metal roofs require less material which reduces the overall load on the building s structure. See the illustration below.

You ll have a steeper part of your roof turning into a lower slope so there s a steeper pitch up top and a lower pitch on the bottom. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. We re going to do a pitch transition or change. The minimum slope for lapped non soldered seam metal roofs without applied lap sealant shall be three units vertical in 12 units horizontal 25 percent slope.

Minimum metal roof slope depends on the roof profile building design climate and site location. Repeat step 3 on the opposite end of the roof transition. The roof plane goes from one pitch to a lower pitch. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

The minimum slope for lapped non soldered seam metal roofs with applied lap sealant shall be one half unit vertical in 12 units horizontal 4 percent slope. Install bottom roofing panels first. Just simple 3d animated digital instructions on how to install transition trim on a masterrib metal roof. After bottom roofing panels have been installed set one piece of transition flashing down where the top portion non hemmed of the transition flashing lies flat on the upper roof.

A roof pitch transition is a line in the roof plane that changes pitch. Measure 1 1 2 from bottom edge of transition flashing. No sales pitch or other fluff. We see this quite frequently in log home roofs with porches for example.
